Sensor-based brick sorting and potential
for recycling

Building rubble is made up of demolished structural concrete and masonry rubble. The latter is heterogeneous, i.e., it is made up of clay bricks, mineral bonded masonry blocks and various minor constituents. For the sake of simplicity, it can be said that recycling rates decrease in inverse proportion to the rubble‘s heterogeneity. Through the year 2020, the Closed Substance Cycle Waste Management Act of March 2011 is promoting the use of waste of all descriptions as secondary raw materials, the aim being to conserve raw materials and save landfill volume. If the targeted 70% recycling rate...
